Lyoto vs Tito- I think Lyoto has great takedown defence, is a much better rounded fighter, and will tag Tito often enough to make him look stoopid and grind out a decision.

Wanderlai vs Jardine- Wanderlai is much more aggressive than chuck, so I don't see Jardine just hanging back and tagging the kicks to get the decision. I see this ending second round by brutal knees to the face

Bj vs sherk- **** if I know. BJ Penn seems to have the force of unstoppable destiny here, but it's really too much of each other's kryptonite.

Sherk's only been beaten before by people outwrestling him- which Penn can't do. He's also got great striking defense and is just hard as **** to rock. I'm not sure how penn is gonna put him on his back. Further, Penn's weakness is cardio, and Sherk has the best in the business(barring perhaps, Urijiah Faber)

......on the other hand I could say most of this stuff about Matt Hughes, who's a bigger,stronger sean sherk. And we know full well that BJ penn has whipped him some wrestlers.

Wanderlei, if he's woken up and started training for real, should demolish Jardine by aggro-clinch.

I'd say that Penn's plan is to put Sherk on his back by knocking him there with his fists and will do his jiu-jitsu magic from there. Sherk might be able to get him down with one of his super-mega-double legs, but Penn is fully capable of owning from his back as well. This'll be interesting but I just don't think Sherk is capable of threatening Penn standup or on the ground and can only really win by lay-n-praying for as many rounds as possible to hopefully chip away at Penn's endurance and then trying to score points in the last round.

Machida-Ortiz
I've got a very clear picture of how this one is going to go, and I see it going a lot like the Forrest Griffin fight. Except Machida is better than Forrest.
Round 1: Machida completely controls the fight on the feet but doesn't do much damage. Avoids a takedown or two, but then gets pushed against the fence and ends up on the floor. Machida controls Tito in his guard though and only catches 1 or 2 elbows. They get stood up and Machida lands a good left hand or two to end the round.
Round 2: Tito gets frustrated by Machida's standup and his takedowns become increasingly sloppy. Machida continues to pepper and frustrate him with jabs and body kicks, and late in the round gets Tito on his back with a Sumo-style trip. Tito avoids any damage, but Machida has all the momentum by the end of the round.
Round 3: Machida is able to keep it on the feet the whole time. He never really rocks Tito but hits him with a spinning back kick, a few knees from the clinch and a straight left or two after stuffing a takedown.
Unanimous Decision, Machida.

Jardine-Silva
Depends on which Wandy shows up...if he's aggressive, he wins. If he fights like he did against Chuck, he loses. I think Jardine handles Wandy like he did Chuck. If he can avoid the clinch, throw leg kicks and straight punches he gets the decision easy. If Wandy gets him in the Thai clinch though, it's over. Houston Alexander exposed Jardine's weakness in the clinch.

Penn-Sherk
Lack of steroids will be Sherk's undoing. Really. They'll trade punches through rounds 1 and 2, with Penn winning most of it but Sherk landing a few hard shots. Sherk will get a takedown or 2 but will be controlled by BJ's guard. By the end of round 2 BJ will be slightly behind, but at the start of round 3 Sherk will be noticeably gassed. He'll get sloppy on a shot, BJ will take his back and submit him with a RNC before the halfway point. Yes, BJ Penn will out-cardio Sean Sherk.
